This is the second time I track my M3 here. The last time was 2 years ago, brand new car with 1800km milage (Lap time2:31.76).
In this video, the rear tires are still the ones I used 2 years ago, 18000km PS4S. The front tires are brand new PSS. 
The car is still twitchy, but as long as managing the throttle carefully, it does the job.
I am quite happy with the lap time, more than 2 seconds faster. ​This proves that both my driving skills and understanding of this track have significantly improved. Yes, the new track surface paving probably also helped.
